Added support to MachO.h for many defines and structures that are needed
to Parse mach-o files. All defines have been renamed to not conflict with
#defines in mach header files, all structures were left named the same but
are in the llvm::MachO namespace.

Eliminate the restriction that metadata kind IDs can't be 0.

start straightening out libedis's dependencies and make it fit
better in the llvm world.  Among other things, this changes:

1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
   so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
   API depends on it.
4. Various code cleanup changes.

There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.

Don't hoist things out of a large switch inside a
loop, for the reasons in the comments.  This is a
major win on 253.perlbmk on ARM Darwin.  I expect it
to be a good heuristic in general, but it's possible
some things will regress; I'll be watching.

sink the arm implementations of ASmPrinter and MCInstLower
out of the AsmPrinter directory into libarm.  Now the
ARM InstPrinters depend jsut on the MC stuff, not on vmcore
or codegen.

fix a layering problem by moving the x86 implementation
of AsmPrinter and InstLowering into libx86 and out of the
asmprinter subdirectory.  Now X86/AsmPrinter just depends on
MC stuff, not all of codegen and LLVM IR.

After a custom inserter, in a block which has constant instructions,
update the current basic block in addition to the current insert
position, so that they remain consistent. This fixes rdar://8204072.

ARM has to provide its own TargetLowering::findRepresentativeClass because its scalar floating point registers alias its vector registers.

Change the implemented interfaces list on PassInfo from a std::vector to a manually implemented
linked list.  This is a little slower and involves more malloc'ing, but these lists are
typically short, and it allows PassInfo to be entirely constant initializable.

Save a copy of the unstripped libLTO.dylib in $SYM_DIR.  Clean up the code
for dealing with libLTO.dylib to put it all in one place and to allow

MC/Mach-O: Silently ignore .file directives instead of error'ing out on
them. They aren't important enough to abort the entire assembly, and failing
early makes testing more annoying.

X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same
instruction, we only want to allow the one for the current subtarget.
 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.
